Foldable electronic device

Abstract

A foldable electronic device including a main frame, a display and a pivot is provided. The main frame includes a photo catalyst disposed on the surface thereof The display includes an ultraviolet light source for illuminating the photo catalyst disposed on the main frame. The main frame is pivoted on one side of the display through a pivot, so that the display can rotate relatively to the main frame. When the main frame and the display are closed, the photo catalyst is exposed to ultraviolet light generated from the ultraviolet light source for sterilization.

1 . A foldable electronic device, comprising: 
 a main frame, a photo catalyst being disposed on a surface of the main frame;    a display comprising an ultraviolet light source for illuminating the photo catalyst disposed on the main frame; and    a pivot disposed at one side of the main frame and the display, such that the display can rotate relatively to the main frame.    
   
   
       2 . The foldable electronic device according to  claim 1 , wherein the display comprises: 
 a display panel; and    a first backlight module disposed on one side of the display panel, and the ultraviolet light source disposed in the first backlight module.    
   
   
       3 . The foldable electronic device according to  claim 2 , wherein the first backlight module comprises: 
 a first light-guiding plate having a first light incident surface and a second light incident surface, wherein the ultraviolet light source is disposed beside the first light incident surface; and    a white light source disposed beside the second light incident surface for providing light which the display panel needs.    
   
   
       4 . The foldable electronic device according to  claim 3 , wherein the white light source comprises a cold cathode fluorescent lamp or a light emitting diode array.  
   
   
       5 . The foldable electronic device according to  claim 1 , wherein the display comprises: 
 a display panel;    a second backlight module disposed at one side of the display panel; and    a second light-guiding plate disposed at the other side of the display panel, wherein the ultraviolet light source is disposed beside the second light-guiding plate.    
   
   
       6 . The foldable electronic device according to  claim 5 , wherein the second backlight module comprises: 
 a third light-guiding plate; and    a white light source disposed beside the third light-guiding plate for providing light which the display panel needs.    
   
   
       7 . The foldable electronic device according to  claim 6 , wherein the white light source comprises a cold cathode fluorescent lamp or a light emitting diode array.  
   
   
       8 . The foldable electronic device according to  claim 1 , wherein the material of the photo catalyst comprises titanium dioxide.  
   
   
       9 . The foldable electronic device according to  claim 1 , wherein the main frame further comprises an ultraviolet light source switch, when the foldable electronic device is closed and the ultraviolet light source switch is turned on, the ultraviolet light source switch is suitable for emitting an ultraviolet light.  
   
   
       10 . The foldable electronic device according to  claim 1 , wherein the ultraviolet light source comprises an ultraviolet tube.  
   
   
       11 . The foldable electronic device according to  claim 1 , wherein the main frame further comprises a touch panel and/or a keyboard, and the photo catalyst is disposed on the surface of the touch panel and/or the keyboard.
